Tom Stellard's presentation 

At the XDC2011, we discussed how GPGPU should be handled and we kind of agreed
on what we should do. This can basically be summed up as using the LLVM IR for
compute. This means we need to implement LLVM backends for our GPUs. See the
Mesa_compilers.pdf attachment.

The OpenCL frontend has been implemented by Denis Steckelmacher during the GSoC 2011 (https://steckdenis.wordpress.com/2011/08/23/the-gsoc-is-over/) that currently works on the CPU only.

This implementation work can be done by a newcomer, it requires knowledge (or willing to get it) in compilers. Please contact Martin Peres(mupuf) to get started. We'll see who can mentor your work.

It appears that this bug report has laid dormant for quite a while. Sorry we haven't gotten to it. Since we fix bugs all the time, chances are pretty good that your issue has been fixed with the latest software. Please give it a shot. (Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git versions.) If upgrading to the latest isn't an option for you, your distro's bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs that haven't seen updates since 2011. If the original issue remains, please make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/ for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
